Description
The FOD3180 is a 2A Output Current, High Speed
MOSFET Gate Drive Optocoupler. It consists of a
aluminium gallium arsenide (AlGaAs) light emitting diode
optically coupled to a CMOS detector with PMOS and
NMOS output power transistors integrated circuit power
stage. It is ideally suited for high frequency driving of
power MOSFETs used in Plasma Display Panels
(PDPs), motor control inverter applications and high
performance DC/DC converters.
The device is packaged in an 8-pin dual in-line housing
compatible with 260°C reflow processes for lead free
solder compliance.

Absolute Maximum Ratings
(T
A
= 25°C unless otherwise specified)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.

Notes:
1. Derate linearly above +70°C free air temperature at a rate of 0.3mA/°C.
2. The output currents IOH and IOL are specified with a capacitive current limited load = (3 x 0.01µF) + 0.5Ω,
frequency = 8kHz, 50% DF.
3. The output currents IOH and IOL are specified with a capacitive current limited load = (3 x 0.01µF) + 8.5Ω,
frequency = 8kHz, 50% DF.
4. Derate linearly above +87°C, free air temperature at the rate of 0.77mW/°C. Refer to Figure 12.
5. No derating required across operating temperature range.
6. In this test, VOH is measured with a dc load current of 100mA. When driving capacitive load VOH will approach VCC
as IOH approaches zero amps.
7. Maximum pulse width = 1ms, maximum duty cycle = 20%.
8. tPHL propagation delay is measured from the 50% level on the falling edge of the input pulse to the 50% level of the
falling edge of the VO signal. tPLH propagation delay is measured from the 50% level on the rising edge of the input
pulse to the 50% level of the rising edge of the VO signal.
9. PWD is defined as | tPHL – tPLH | for any given device.
10. The difference between tPHL and tPLH between any two FOD3180 parts under same test conditions.
11. Pin 1 and 4 need to be connected to LED common.
12. Common mode transient immunity in the high state is the maximum tolerable dVCM/dt of the common mode pulse
VCM to assure that the output will remain in the high state (i.e. VO > 10.0V).
13. Common mode transient immunity in a low state is the maximum tolerable dVCM/dt of the common mode pulse,
VCM, to assure that the output will remain in a low state (i.e. VO < 1.0V).
14. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000Vrms,
60Hz for 1 second (leakage detection current limit II-O < 5µA).
15. Device considered a two-terminal device: pins on input side shorted together and pins on output side shorted
together.

Reflow Profile
Output Power Derating
The maximum package power dissipation is 295mW. The
package is limited to this level to ensure that under normal
operating conditions and over extended temperature
range that the semiconductor junction temperatures do
not exceed 125°C. The package power is composed of
three elements; the LED, static operating power of the
output IC, and the power dissipated in the output power
MOSFET transistors. The power rating of the output IC is
250mW. This power is divided between the static power of
the integrated circuit, which is the product of IDD times the
power supply voltage (VDD – VEE). The maximum IC
static output power is 150mW, (VDD – VEE) = 25V, IDD =
6mA. This maximum condition is valid over the opera-
tional temperature range of -40°C to +100°C. Under these
maximum operating conditions, the output of the power
MOSFET is allowed to dissipate 100mW of power.
The absolute maximum output power dissipation versus
ambient temperature is shown in Figure 12. The output
driver is capable of supplying 100mW of output power
over the temperature range from -40°C to 87°C. The out-
put derates to 90mW at the absolute maximum operating
temperature of 100°C.
The output power is the product of the average output
current squared times the output transistor’s RDS(ON):
PO(AVG) = IO(AVG)2 • RDS(ON)
The IO(AVG) is the product of the duty factor times the
peak current flowing in the output. The duty factor is
the ratio of the ‘on’ time of the output load current divided
by the period of the operating frequency. An RDS(ON) of
2.0Ω results in an average output load current of 200mA.
The load duty factor is a ratio of the average output time
of the power MOSFET load circuit and period of the driv-
ing frequency.
The maximum permissible, operating frequency is deter-
mined by the load supplied to the output at its resulting
output pulse width. Figure 13 shows an example of a
0.03µF gate to source capacitance with a series resis-
tance of 8.50Ω. This reactive load results in a composite
average pulse width of 1.5µs. Under this load condition it
is not necessary to derate the absolute maximum output
current until the frequency of operation exceeds 63kHz.

FOD3180 — 2A Output Current, High Speed MOSFET Gate Driver Optocoupler
IOH and IOL Test Conditions
This device is tested and specified when driving a com-
plex reactive load. The load consists of a capacitor in the
series with a current limiting resistor. The capacitor rep-
resents the gate to source capacitance of a power
MOSFET transistor. The test load is a 0.03µF capacitor
in series with an 8.5Ω resistor. The LED test frequency is
10.0kHz with a 50% duty cycle. The combined IOH and
IOL output load current duty factor is 0.6% at the test
frequency.
Figure 14 illustrates the relationship of the LED input
drive current and the device’s output voltage and sourc-
ing and sinking currents. The 0.03µF capacitor load rep-
resents the gate to source capacitance of a very large
power MOSFET transistor. A single supply voltage of
20V is used in the evaluation.
Figure 15 shows the test schematic to evaluate the out-
put voltage and sourcing and sinking capability of the
device. The IOH and IOL are measured at the peak of
their respective current pulses.

LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used herein:
1. Life support devices or systems are devices or systems which, (a) are
intended for surgical implant into the body or (b) support or sustain life,
and (c) whose failure to perform when properly used in accordance
with instructions for use provided in the labeling, can be reasonably
expected to result in a significant injury of the user.
2. A critical component in any component of a life support, device, or
system whose failure to perform can be reasonably expected to
cause the failure of the life support device or system, or to affect its
safety or effectiveness.
ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.
Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failedapplications,
and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of
counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are
listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have
full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technicaland product information.
Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide
any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buying direct or from authorized distributors.
